1 Claim.

This invention relates to improvements in Venetian blinds and more especially to new and novel means which enable the slats of the blind to be quickly and conveniently removed from their suspending tapes and actuating cords for cleaning or replacement purposes.

A further object of the invention is the provision of means of this character which will remain permanently attached to the cords at all times so that they will not become lost or misplaced.

A further object of the invention is the provision of a device of this character which is of simple, efficient, durable, and inexpensive construction; readily adaptable to slats in their process of manufacture, and which may also be applied to standard or conventionally slotted slats already in use and at a very low cost.

A still further object is the provision of a device of this character which is readily adaptable to Venetian blind slats of either the fiat or curvilinear form in cross section.

These and other objects will appear as our invention is more fully hereinafter described in the following specification, illustrated in the accompanying drawing and finally pointed out in the appended claim.

In the drawing:

Figure 1 is a perspective view of a fragment of a Venetian blind slat equipped with our invention.

Figure 2 is a composite view showing a fragment of a slat transversely slotted, and a fastening element adapted for engagement with the slot.

Figure 3 is a perspective view of a fragment of a metallic slat of curvilinear form in cross section and showing our invention of corresponding shape applied thereto.

Figure 4 is a perspective view of a blank piece of material having aligned openings punched therein as shown and adapted to be folded over on itself to form a grip as illustrated in Figure 5.

Referring now more particularly to the drawing:

In Figures 1 and 2, reference numeral I indicates' a conventional wooden slat as used in "Venetian blinds. Each slat is slotted for the major portion of its width as indicated at 2 and one end of the slot is open as shown. These slots may be formed in the process of manufacturing new slats or in slats already in use by merely cutting out one end of the existing slot. For snug slidable engagement with the inner end and marginal edges of each slot, we provide an elongated plate 3 slotted along its longitudinal axis as shown to form flanges 5 and 6 along two of its sides and across one end. The body of the plate at the flanged end may be left square or may be rounded to conform to the closed end of the slot 2. When the plates are attached to the slats they remain firmly in place throughout all the manipulation of the blinds such as raising, lowering or tilting the slats. The actuating cords I extend through the slot 4 in each plate as shown and as each plate is detached from the slat to be removed, the plates all slide to the bottom of the cord from where they may be lifted and spaced to re-engage the slats upon re-assembling the blind.

The modified form of the invention illustrated in Figure 3 is substantially the same as that shown in Figures 1 and 2 except that it is of curvilinear form in side elevation and made of thinner material for engagement with metallic slats.

The further modified form of the invention shown in Figures 4 and 5 consists of an elongated strip of metal 8 formed with elongated openings 9 and I0 which are brought into registry with each other when the strip is folded over on itself as shown in Figure 5 to form a spring clip.

While we have shown a particular form of embodiment of our invention, we are aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the inven tion.

Having thus described the invention, what we claim as new and desire to protect by Letters Patent is:

In a blind having a plurality of slats slidably and swingably mounted on suspending cords, each of said slats having a plurality of transverse slots cut inwardly from one longitudinal edge of the slat, a cord embracing element adapted for frictional engagement with the slat, said element comprising an elongated strip of material of greater width than that of the slot and having two spaced apart elongated apertures formed therein, said strip of material adapted to be folded over on itself into gripping engagement with both sides of the slat about the marginal edges of the slot and to bring said apertures into alignment with each other as a single opening for the passage of said suspending cord therethrough.
